I've heard a lot of good things about Goose Island beers, but haven't had the opportunity to have any. Currently, my top "sessionable" beer is Bell's Two Hearted Ale. The brewery is in Kalamazoo, Michigan.

Yes, cans are actually the best way to package beer (other than kegs - stainless or oak). Heini's green bottles let in the particular wavelength of light required to alter the hop character to the well known skunk aroma.

But there is a stigma attached to cans, so bottles get the nod. Brown is best for preserving all the intended character of the brew.
